TO ALL WHOM IT MAY CONCERN: 7

Be it known that I, ABRAM REESE, of Pittsburg, in thecou'nty of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Machine for Forming Horse-Shoes; and I do hereby declare the following to be a. full, clear,-and exact description thereof.

The object ofmy improved machine is to cutand form horse-shoes, by bending and pressing, from iron bars previously rolled into a. series'or succession of horse-shoe blanks, each consecutive blank being of the requisite length, and properly creased and flared or bevelled for a properly-shaped horse-shoe. Such bars or series of blanks are rolled by machinery constructed for and adapted to such use from common or horse-shoe bar iron, and are then ready to be fed into the machine I am about to describe.

The nature of my invention may be sutliciently stated by' referring to its leading features, which are, feeding a bur er series of'blanks such as is above described, by an intermittent motion under a tripping blade or cutter, by which the blanks are successively cut off, bending the ends of the blank so severed over a former by lugs projecting from the cylindrical face of a revolving disk or roll, in combination with properly-shaped guides for giving the sides of the shoe the desired curvature, and in discharging the shoe from the former when bent into shape, and pressing it to remove such objectionable curvature as may be given to the shoe by the peculiar shape of the apparatus that bends it.

To enable others skilled in the art to make and use my invention, I will proceed more particularly to' describe its construction and mode of operation, referring for that purpose to the drawings hereto annexed, making-a part of this specificatiomin which- Figure 1 is a perspective view of my machine, except the feeding movement represented in section in fig. 4.

Ifigure is a sectional elevation through the disk, former, &-c., at right angles to the axle of the disk.

Figure 3 is an inner face view of the former, face-plate, guides, &c., as represented by a section,through the line 3 y, fig. 2. V i

Figure 4 shows in section the feeding movement, as formed by a vertical plane passing through the line zz, fig; 3.

Like letters of reference indicate like parts of each.

The devices I employ are attached toand supported by any suitable framework, A, and operated by steam erother power communicated through a crank or otherwise, at pleasure. B is a disk or cylinder revolving on its axle, G, which latter operates in bearings, c, of any desirable construction. To one end of the axle O is attached the bevel gear-wheel D, which is furnished with cogs over but half or other fractional part of its bevel face. These cogs play into the cogs of the correspondingbevel-gear or pinion-wheel E, which, through its axle e, actuates the grooved feed-roller f. One end a of the frame A has an inner metallic face-plate a, notched to receive the horse-shoe former b, the outer edge of which is of the shape to be given to the horse-shoe to be made. This former Z2 ordinarily projects forward of the faceplate a about the thickness of the shoe-blank! At either side are the inclined guides d, for use as yet to be explained. Also attached to the upper part of the frame A is the guiding-plate g, folded over and forward of the face-plate a a sufiicient distance to admit behind or under it, and over-the former b, the bar or blanks to be bent into horse-shoes. This guiding-plate g is notched or slotted at certain intervals for purposes hereinafter to appear. The former b rests against and is secured to an upright bar, it, pivoted at or near its upper end to the framework a, and-its lower end bent forward toward the disk B, and bifurcated, as at it. Springs a" are to be used, if found necessary, to keep the form or b to its place. Pivoted to any convenient part of the frame, as at Z, is the cutting blade m, one arm extending back and operated by the tripper n in the axle O, and the other arm with a cutting edge operating through a slot, x, in the guiding-plate g to cut the bar or blank. In actual use, a bar or series of blanks, such as is above described, resting on the edge which is'to form the inside of the shoe, is introduced between the feed-rollers ff By these it is carried forward and passed under or back of the guiding-plate g by the guide, g, fig. 1, the gearing described beingso arranged that as soon as one blank shall have passed the end of the cutter m, the feed motion shall cease, and the trippcr 'it causethe cutter m to sever the bar. At the same time the cam-shaped flange b, on the outer or cylindrical face of therevolving disk B, by coming in contact with and pressing against the guiding plate 9, holds the middle of the blank firmly in its place directly over the former 6. Attached to or insertcd in the sides of the disk B, and secured by bolts 0", are the arms 0 0, which project forward through the slotted plate q, and terminate in heads or lugs 0 0' on opposite sides of the flange b. 7 Such arms, 0 o, are made somewhat flexible, so as to admit of a slight lateral motion, and are fitted to thesl'otted plate qin such a way as to be supported in the direction of their revolution, and left free to approach to or recede from the flange b. A friction-roller, e, is also pivoted on the outer or cylindrical face of the disk B, and asclose as it can conveniently be placed to the thick end of the flange b and to the lugs 0' 0. As the revolution of thedisk Bis continued the lugs 0 0 pass through the slots or notches 2; x in the guiding-plate g, engage the blank for the shoe on its upper edge on either side of its middle point. As the disk' B continues to turn, the lugs 0 0 bond the ends of the horsc-shoe blank downwards over the former b, the middle partof the blank being still held above the former b in the manner alreadystatedr. Further down the lugs 0' 0' strike the inclined guides ziby which they are turned inwards, and the sides of the shoe toward the-toe made to hug closely the sides of the former b. The lugs o 0 and the working edges of the guides cZ dtshould be so made as to avoid friction and resistance as perfectly as possible. By these means each blank is severed from its parent bar, and' bent over or around a properly-shaped former into a horc-shoc shape. The roller 0 next engages the arms 2' 2' ofthe bifurcated swinging bar-7i, throws the bar back, whereby the former b is alsocarried back, and the horse-shoe is discharged therefrom, falls downwards, passing between the arms 2'2 till it is caught by the pressing-boardspp. The pressure to which the shoe has been subject against the concave face-plate a, as well as the direction of the bending motion, have made it slightly concave or distorted. To remove this concavity I apply to it a moderate pressure between the pressing-boards 1919. The motion requisite for this purpose I obtain by inserting a tripper in the axle C, at such a pointthat as the shoe is disengaged from the former I), this tripper will carry forward the bent lover s, to which one pressing-board, p, is attached, and press'the shoe against the opposite and stationary pressing-board, p. The

shoe is thus caught and pressed, after which the pressing-board is carried back by the elastic springs t t conncctcd therewith, and the shoe discharged in the condition required for market. The former b may, if so preferred, be stationary, in which case the shoclmay, after being bent, as above described, be discharged therefrom by fingers attached to a swinging bar or cam movement, such fingers working through holes 8 s in the face-plate a and on opposite sides of the former I). If found necessary, a rubber or other spring, r, may be placed between the arms 0 o to keep them well separated, except when made to approach each other by the inclined guides (Z (Z. I

For making shoes from blanks of different lengths, or, if preferred, for making shoes from blanks of uniform length, the proper intermittent motion can be obtained by attaching a clutch device of the ordinary construction, and operated'in the ordinary way, to the pinion-shaft e. In this way the working of the machine can be regulated for blanks of all lengths usually made. In the feeding movement described either or both the rollers ff may be grooved, the object being merely to feed the bar in on its edge, as above described.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is'- 1. A former, either fixed or movable, and of the shape of the inside of a horse-shoe, in combination with flexible arms 0, fitted with lugs 0, attached to and operated by a revolving disk or cylinder, and guides d d, and flange l), or their mechanical equivalents, for bending horse-shoe blanks, substantially as and for the purposcs-hcrcinbeforc set forth.

2. Discharging the shoe when bent around the fixed or movable former b by a roller, 0, operating against the lower end of a bent swinging bar, It, to which the former is attached, substantially as and for the purpose hercinbcfore set forth.

In testimony whereof Iflhe @JLTABRAXI REESE, have hereunto set my hand in presence of- ABRAM REESE.
